Product Description

THE INNOVATION

Off road: Riding at lower pressure means better performance ... but at the same time it increases the risk of failures. The limit so far is at about 20 psi, below which it’s hardly possible to dare to ride normal MTB tires.

But nothing stays the same:
In the future, air pressure can be controlled in the tire‘s double chambers. In the outer chamber, the air pressure is extremely low - ideal for maximum off road performance. In the inner chamber, directly on the rim, there is high air pressure – even a very strong impact cannot dent the rim edge. At the same time, the inner high-pressure system secures the tire onto the rim. “Burping”, the dreaded loss of air at low pressure in conventional tubeless systems, is impossible.

The name
PROCORE is derived from "Progressive Core". The core (internal high pressure chamber) progressively absorbs even the hardest impacts.

The compatibility
You can mount Procore with any tubeless compatible MTB tire. The system is available for all three MTB wheel sizes (26“, 27.5“, 29“). Weight approx. 200 g per wheel. Compatible with all wheels, independent of the brand. Minimum inner rim width: 23 mm.

PROCORE is a joint development of SCHWALBE and SYNTACE.


THE DESIGN


PROCORE - the outer chamber
The outer chamber is tubeless. Therefore, any tubeless compatible MTB tires can be used. The tire is filled with some liquid sealant (approx. 60 ml) and should be at least 57 mm (2.25“) wide.

PROCORE - the inner chamber

Two special Procore components form the inner high pressure chamber: the special Procore tube and the Procore inner tire. This "core" is extremely high pressure stable and at the same time very light.

The rim

Of course, the rim must be tubeless compatible and sealed with a tubeless rim band. It should have an inner rim width of at least 23 mm. The wider the rim, the easier the installation and the better the performance under low air pressure. The very wide Syntace rims are a perfect fit.

The PROCORE valve

The patented dual valve of the Procore tube distributes the air into both chambers. The upper part of the valve is a selector. With a simple turn, you select whether air is pumped into the inner or the outer chamber.

The PROCORE Air Guide

The small red component made of white plastic ensures that the air can flow past the inner high pressure chamber into the outer low pressure chamber.


THE BENEFITS

    Tire pressure can be reduced to a minimum 14 psi, thus giving a huge amount of grip. Even on the roughest terrain tires “stick” to the ground.

    The tire gives extremely sensitive cushioning.

    Due to the extra cushioning and traction there is much better steering, braking and traction control.

    No more risk of snake bites. The rims are extremely well protected from denting.

    Even in the toughest conditions, significantly lighter tires can be used.

    Excellent emergency running characteristics due to the internal high-pressure air chamber.


THE FITTING PROCESS


Prerequisites:

    tubeless compatible tire, minimum width 57 mm (2.25”)
    tubeless compatible wheel, minimum rim width 23 mm (with rim widths of 21 or 22 mm the installation can turn out to be very difficult)

Doc Blue Professional

New Doc Blue: Now even better formulated for Tubeless conversions. Produced by Stan’s NoTubes! It can also be used as a puncture potection preventative for bicycle tubes, tubular tires and standard Tubeless systems.

Dose: 
60 ml/tire (Race bike 30 ml). Effective ca. 2-7 Months. Thereafter dries to a rubber film. Can be renewed. Only suitable for tubes with a removable valve core. Not effective on large defects (cuts/bursts).


Tubeless Rim Tape

The tubeless rim tape is extremely user friendly and at the same time very high pressure resistant. Even on road bikes a single ply of tape is sufficient.


Tire Levers

Tire changing made easy! The special shape of the lever reduces the danger of the tube being pinched during installation. When removing a tire, the lever can be snapped onto the spoke – leaving hands free for the second lever. The high-quality plastic is virtually unbreakable. Levers can be clipped together for easy storage.

Occasionally, without notice, manufacturers change product design and/or specifications.

Inner Tubes Size Guide

 

Inner Tubes Guide

What Size Inner Tube Do I Need?

Follow these three simple steps to find the right size inner tube for your bike.

Wheel size diameter on tyre sidewall for correct inner tube sizing

1. Wheel Size

Inner tubes are made to fit specific wheel sizes, so you need to know what size the wheel on your bike is.

The easiest way to do this is by looking at the tyres on your bike. On the sidewall you'll see a combination of digits such as:

700 x 28c (road bike wheel) or 27.5 x 2.4 (mountain bike wheel)

It’s the first figure that shows the diameter of the wheel or the wheel size.

The next figure is tyre width which is the other measurement you need to know.

Wheel size diameter on tyre sidewall for correct inner tube sizing

2. Tyre Width

Inner tubes are designed to fit a range of tyre widths, so the next thing you need to know is the width of your tyre.

This is shown in the second number that’s printed on the side of the tyre.

700 x 28c (road bike wheel) or 27.5 x 2.4 (mountain bike wheel)

When choosing an inner tube you need one with a width range that covers your tyre width as well as exactly matching the size of the wheel. See the tables below for examples.

Note: Sometimes metric sizes are shown as c instead of mm. This is just a different way of saying the same thing. A 25c tyre is the same width as a 25mm tyre.

3. Valve Type

There are two types of inner tube valve; Shrader and Presta. The easiest way to see which one you need is to look at the tube on your bike.

Schrader Valve

Schrader Valve

Easily identified by the 'car type' stubby profile.

These valves are often found on entry-level hybrid, mountain and kids bikes which run on lower tyre pressures.

It is worth noting that Schrader valves require a slightly larger hole in the rim. This means that you can use Presta valve tubes on a Schrader compatible wheel rim but not the other way around.


Presta Valve

Presta Valve

These have a long and narrow profile. They have a central core you unscrew before inflating the tube.

Presta valves are often used on road bikes which run at higher tyre pressures as well as mid to high-end mountain bikes.

These valves come in a range of lengths. Longer valves are designed for use with deep section aero rims.



ETRTO bike tyre sizing can be found on tyre sidewall

My tyre size looks different - ETRTO Sizing

Sometimes tyre size on the sidewall of your tyre is shown in the ETRTO format like this 54-559 or 23-622. ETRTO size tyres are the same size as Imperial / Metric tyres, it’s just that the measurements are shown differently.

All our inner tubes are listed in Metric or Imperial sizing but you can use the table below to convert your ETRTO size to Imperial for MTB tyres or Metric for road bike tyres.

The Benefits Of Self-Sealing Inner Tubes

Punctures are inevitable. Instead of having to lug around spare inner tubes with you, you can opt for a self-sealing inner tube. These bike inner tubes are delivered with tube sealant already inside. When you get a puncture the sealant will plug the gap so you can keep riding.
